BMW’s new Vision Efﬁcient Dynamics concept is remarkable to look at and even more so when you consider the numbers. Powered by a three-cylinder turbodiesel and two electric motors (one in each axle), the all-wheel drive produces 262 kW (356 bhp) and 800 NM of torque, giving it M power performance (0-100 km/h in 4.8 seconds and an electronically limited top speed of 250 km/h) thanks in part to its slippery drag coefﬁcient of just 0.22. It’ll run 50 km (31 miles) in electric mode alone and its consumption in the EU test cycle is 3.76 litres/100 km (75.1 mph imp) with CO2 emissions of 99 grams/km.
